ATLANTA -- The Atlanta Braves have agreed with pitcher Craig Kimbrel to terms on a four-year contract, the team announced Sunday.

The agreement means Kimbrel and the Braves will not have to go into salary arbitration. Financial details were not released.

"We are very excited to agree to terms with Craig, who we feel is the best closer in Major League Baseball," Braves executive vice president and general manager Frank Wren said in a release. "He is one of the key pieces of our pitching staff, and we are happy to keep him in a Braves uniform for at least four more years."

The 25-year-old pitcher was named to the National League All-Star team in 2013 for the third year in a row. He is also the youngest pitcher in MLB history to notch 50 saves in a season, and is only 15 saves shy of John Smoltz's franchise record of 154 career rescues, according to the Braves.

Kimbrel was drafted by the Braves in 2008 and made his MLB debut during the 2010 season.
